Description

  The present invention relates to a recording apparatus that records a video source such as a broadcast program, reproduces the recorded video source, and outputs the recorded video source to an external TV monitor or the like via a video output terminal.

  In a conventional recording apparatus, a source signal during recording is output from a video output terminal for outputting a video source to an external monitor (usually a television receiver). This is mainly used for the purpose of the user confirming the recording source. In addition, there is a device with a dedicated switch for switching the output of the video output terminal. Similarly, this device also outputs the output status of the video output terminal during the recording start operation. It is comprised so that it may switch to.

  By the way, the recording device has a reserved recording function. When executing scheduled recording, the reservation setter usually takes the form of leaving home and viewing after returning home, that is, after the recording of the program ends. However, when you go home before the scheduled recording is finished and turn on the TV monitor to which the recording device is connected, you will unintentionally watch the middle of the program that is currently being recorded and enjoy watching the program from the beginning. There is a problem of losing.

  Recently, recording / playback apparatuses such as hard disk recorders and DVD recorders are capable of recording a program and simultaneously viewing a recorded program different from the program being recorded. In such an apparatus, there are situations in which a recorded program is reproduced not only when the viewer is away from home but also at home. In this case, when the reproduction of the recorded program is terminated and a stop operation or the like is performed, the program that is currently being recorded may be viewed unintentionally. Of course, this situation is not limited to the reserved recording operation, and the same situation can be obtained after recording is started manually and another recorded program is reproduced at that time.

  The present invention is for solving the problems of such a conventional recording device, and in either case of reserved recording or manual recording, the viewer is against the intention of the video in the middle of the currently recorded program, Alternatively, it is an object of the present invention to provide a recording apparatus that can prevent an accidental viewing.

In order to achieve the above object, the present invention
In a recording apparatus for recording a video source on a recording medium with a timer, reproducing the video source recorded on the recording medium and outputting the video source to the outside via a video output terminal.
Video output control means for outputting the video source currently being recorded to the outside via the video output terminal during the timer recording execution and outputting according to the reproduction operation after the timer recording is released ,
During the timer recording of the video source from the tuner externally connected to the recording device to the recording medium, the tuner built in the recording device cannot be switched to the same channel as the timer recording channel. It is characterized by.
In addition, a signal for displaying a screen indicating that recording is being performed is output to the outside via the video output terminal instead of the video source signal being recorded.
Also, a screen displaying a thumbnail in the thumbnail window of the recorded video source instead of the signal of the video source being recorded, and displaying a message being recorded in place of the thumbnail in the thumbnail window of the video source being recorded A signal for displaying is output to the outside through the video output terminal.

  According to the present invention, since the signal of the video source being recorded is prohibited from being output to the outside through the video output terminal, the viewer may dislike the video in the middle of the currently recorded program, or It is possible to prevent mistaken viewing.

Embodiments of the present invention will be described below with reference to the drawings.
<First Embodiment>
FIG. 1 is a block diagram showing a first embodiment of a recording apparatus according to the present invention, and FIG. 2 is a flowchart for explaining the processing procedure of the microprocessor of FIG.

  In the recording apparatus 1 shown in FIG. 1, a video source (including an audio signal) received by the tuner 12 is recorded on the storage medium 13 during recording. During reproduction, the video source reproduced from the storage medium 13 is output to the outside via the changeover switch 14, the display control unit 15, and the video output terminal 16. The microprocessor 10 performs various controls of the memory 11, the tuner 12, the storage medium 13, the changeover switch 14, and the display control unit 15. The display control unit 15 has an information display function unit for displaying screens as shown in FIGS.

  Here, as described above, in the conventional recording apparatus, the video source signal from the tuner 12 is output from the video output terminal 16 during recording. Therefore, there is a possibility that the user unintentionally sees the video source being recorded. In the present invention, in order to eliminate such a possibility, the state of the changeover switch 14 during recording is switched so as to select a source that is not output from the tuner 12 after the start of recording, and the display control unit 15 The user can select / determine a video source signal to be arbitrarily output from the video output terminal 16 by the switching confirmation operation accompanied by the selection / indication display on the screen generated by the above.

  FIG. 2 shows a processing procedure of the microprocessor constituting this embodiment. The microprocessor 10 determines whether or not recording is started (step S1), and outputs a non-recording source (a source other than the video source being recorded) from the video output terminal 16 when recording is started (Yes in step S1) (step S1). Step S2). Examples of non-recording sources are shown in FIGS. As an example, FIG. 3 outputs a display message indicating “recording”, a channel being recorded, a start time, and a scheduled end time. As another example, FIG. 4 displays a thumbnail in the recorded thumbnail window, but displays a “recording” message in place of the thumbnail in the thumbnail window that is being recorded.

  In the recording apparatus 1 shown in FIG. 1, output from the tuner 12 is not output to the video output terminal 16 during reserved recording, and a display indicating that recording is currently being performed is output to the video output terminal 16. Even if the same program as the channel on which the scheduled recording is performed is watched before the scheduled recording starts, a display is made to confirm whether or not to continue the viewing before the recording starts. It is desirable.

  In such a recording apparatus 1, in order to know whether or not the recording has been started reliably, it is certain to output the video of the channel reserved for recording to the video output terminal 16 and confirm it on the monitor screen. Although it is a method, we want to avoid viewing the video being recorded from the middle of the program. For this reason, it is also desirable to display the recording source information as text information (channel number, start time, etc.) as shown in FIG. . In addition to the text information, a device that displays a video output selection screen or a reproduction navigation screen as shown in FIG. 4 can be considered. However, in this case, the currently recorded image is not displayed in the thumbnail window of the navigation screen. In addition, when displaying the recorded part currently being recorded in the thumbnail window, it is conceivable that the reproduction is limited to a certain restricted range such as the beginning part.

<Second Embodiment>
FIG. 5 shows a second embodiment in which the output from the tuner 12 is output to the video output terminal regardless of the selected source position instructed in advance by the display source changeover switch 20 during the reserved recording. 16 shows the recording apparatus 2 that is not output. Here, there is a case where the user wants to intentionally switch the output of the video output terminal 16 to the recording source after the recording is started. In this case, when the user operates the display source changeover switch 20, it is desirable to give consideration such as issuing a caution message before switching the output source of the video output terminal 16. This is not necessarily limited to reserved recording, and there may be a case where it is not desired to view the program until recording ends after manual recording is started. Similarly in this case, the operation of the display source changeover switch 20 does not display a caution message or the like for the recording source, and the output is not immediately switched, so that it is the same as at the start of the scheduled recording. The effect can be expected. Further, when recording is started, the operation of switching the display source changeover switch 20 to another source is performed so that the channel source that has started the recording is not automatically output to the video output terminal 16 without operating the display source changeover switch 20. It is also possible.

<Third Embodiment>
FIG. 6 shows a recording apparatus 3 incorporating a plurality of tuners 121 and 122 capable of outputting the same channel as a third embodiment. In such a recording apparatus 3, during the reserved recording, the video output terminal 16 from any other tuner (eg, tuner 122) is used for the same channel as that of the currently recorded tuner (eg, tuner 121). Do not output to.

<Fourth embodiment>
FIG. 7 shows a recording apparatus 4 for recording input from an external tuner (not shown) connected to the video input terminal 18 as a fourth embodiment. In such a recording apparatus 4, during scheduled recording and recording of an input from an external tuner connected to the video input terminal 18, the microprocessor 10 controls the changeover switch 14 or the video input / output control circuit 17 to control the video output terminal. 16 is not output.

<Fifth embodiment>
FIG. 8 shows a recording apparatus 5 for recording an input from an external tuner built in a TV (not shown) connected to the external apparatus control terminal 19 as a fifth embodiment. In such a recording apparatus 5, the tuner 12 of the recording apparatus 5 does not select the same channel as that of the external tuner during the scheduled recording of the input from the external tuner built in the TV connected to the external apparatus control terminal 19. By doing so, it is possible to prevent the viewer from viewing the video in the middle of the currently recorded program against the intention or by mistake. Alternatively, during the reserved recording of the TV tuner connected to the external device control terminal 19, the tuner 12 of the recording device 5 cannot be switched to the channel being recorded.

<Sixth Embodiment>
